Breda Model 35
The Breda 20/65 mod.35 (''"Breda 20 mm L/65 model 1935"''), also simply known as 20 mm Breda or Breda Model 35, among other variations, was an Italian anti-aircraft gun produced by the Società Italiana Ernesto Breda of Brescia company during the 1930s and early 1940s which saw heavy usage during the Spanish Civil War and World War II, among other period conflicts. It was designed in 1932 and adopted by the Italian armed forces in 1935, becoming one of two major 20 mm caliber anti-aircraft guns used by Italy during World War II, the other being the Scotti-Isotta Fraschini 20/70 (Scotti 20 mm), both firing the common Swiss 20x138mmB "Solothurn Long" cartridge. The Royal Italian Army formally designated the gun Cannone-Mitragliera da 20/65 ( "Cannon-Machinegun 20/65"), with the mount being designated modello 35 (model 1935), or mod.35 for short. Later, a mod.39 (1939) and a mod.40 (1940) system were introduced, featuring the same gun but in new mounts. The ''"20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cannone-Mitragliera Da 20/77 (Scotti)
The Cannone-Mitragliera da 20/77 (Scotti) was a 20 mm anti-aircraft gun produced by the Scotti company in Italy, used in World War II, firing a 20x138mmB cartridge. History The Italian army had two standard 20 mm anti-aircraft weapons during World War II. One was the Breda Breda () is a city and municipality in the southern part of the Netherlands, located in the province of North Brabant. The name derived from ''brede Aa'' ('wide Aa' or 'broad Aa') and refers to the confluence of the rivers Mark and Aa. Breda has ... and the other was the Cannone-Mitragliera da 20/77 (Scotti) which was first designed in 1932 and produced by the Swiss Oerlikon company. They originally used a 60-round drum that was eventually discarded in favor of 12 round trays for the ammunition. Compared to the Breda, the Scotti was a far simpler weapon. It resembled the Oerlikon in some respects, but used a different mechanism. The Scotti was easier to manufacture than the Breda, but despite ...

Spica-class Torpedo Boat
The ''Spica'' class were a class of torpedo boats of the Regia Marina (Royal Italian Navy) during World War II. These ships were built as a result of a clause in the Washington Naval Treaty, which stated that ships with a tonnage of less than 600 could be built in unlimited numbers. Thirty-two ships were built between 1934 and 1937, thirty of which entered service with Italy and two of which were sold to the Swedish Navy in 1940. The two units in Swedish service were classified as destroyers until 1953, then re-classified as corvettes. Although commonly referred to as torpedo boats due to their smaller displacement, the ''Spica'' class armaments were similar in design to destroyers (their design was influenced by the then in development) and were intended for anti-submarine duties, although they often had to fight aircraft and surface forces as well. Twenty-three vessels were lost during World War II. Design The design work started in 1932, and two prototypes, ''Spica'' and ''Ast ...

Swedish Navy
The Swedish Navy ( sv, Svenska marinen) is the naval branch of the Swedish Armed Forces. It is composed of surface and submarine naval units – the Fleet () – as well as marine units, the Amphibious Corps (). In Swedish, vessels of the Swedish Navy are given the prefix "HMS", short for (His/Her Majesty's Ship). In English, this is sometimes changed to "HSwMS" ("His Swedish Majesty's Ship") to differentiate Swedish vessels from those of the British Royal Navy. Founded under King Gustav I in 1522, the Swedish navy is one of the oldest continuously serving navies in the world, celebrating its 500th anniversary in 2022. History Early Swedish kings ( 9th–14th centuries) organised a Swedish Navy along the coastline through . This involved combined rowing and sailing ships (without artillery). This system became obsolete with the development of society and changes in military technology. No later than in the 14th century, the duty to serve in was replaced by a t ...

Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons, based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used today. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on '' Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (' ...

MAS (boat)
''Motoscafo armato silurante'' (torpedo-armed motorboat), commonly abbreviated as MAS, was a class of fast torpedo-armed vessels used by the (Italian Royal Navy) during World War I and World War II. Originally, "MAS" referred to (armed motorboat SVAN, (Naval Automobile Society of Venice). The MAS were essentially motorboats with displacements of 20–30 tonnes (depending on the class), a 10-man crew and armament composed of two torpedoes, heavy machine guns and occasionally a 37 mm or 20 mm cannon. The term "MAS" is an acronym for , (assault craft) in the unit name (assault craft flotilla), the most famous of which was the Decima MAS of World War II. World War I MAS were widely employed by ''Regia Marina'' during World War I in 1915–1918. Models used were directly derived from compact civilian motorboats, provided with petrol engines which were compact and reliable (characteristics which were not common at the time) . They were used not only in the anti-submarine p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corvette
A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper (or " rated") warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern roles that a corvette fulfills include coastal patrol craft, missile boat and fast attack craft. These corvettes are typically between 500 tons and 2,000 .although recent designs may approach 3,000 tons, having size and capabilities that overlap with smaller frigates. However unlike contemporary frigates, a modern corvette does not have sufficient endurance and seaworthiness for long voyages. The word "corvette" is first found in Middle French, a diminutive of the Dutch word ''corf'', meaning a "basket", from the Latin ''corbis''. The rank " corvette captain", equivalent in many navies to "lieutenant commander", derives from the name of this type of ship. The rank is the most junior of three "captain" ranks in s ...

Cannone-Mitragliera Da 37/54 (Breda)
The Cannone-Mitragliera da 37/54 (Breda) was a automatic anti-aircraft gun produced by the Breda company in Italy. It was used by both the Regia Marina The ''Regia Marina'' (; ) was the navy of the Kingdom of Italy (''Regno d'Italia'') from 1861 to 1946. In 1946, with the birth of the Italian Republic (''Repubblica Italiana''), the ''Regia Marina'' changed its name to ''Marina Militare'' ("M ... and the Regio Esercito during World War II, with the former using it as the standard light anti-aircraft weapon on its battleships and cruisers. Nazi Germany used captured weapons after the surrender of Italy in 1943 as the ''3.7 cm Breda (i)''. Design The Model 1932 was water-cooled while Models 1938 and 1939 were air-cooled. The gun was fed by a flat magazine holding six rounds which could be loaded one after another to maintain a high rate of fire. It was possible to select alternate rates of fire, either 60, 90 or 120 rpm. The twin mountings for Models 1932 and 1938 were ver ...

Deck (ship)
A deck is a permanent covering over a compartment or a hull of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. Vessels often have more than one level both within the hull and in the superstructure above the primary deck, similar to the floors of a multi-storey building, that are also referred to as decks, as are certain compartments and decks built over specific areas of the superstructure. Decks for some purposes have specific names. Structure The main purpose of the upper or primary deck is structural, and only secondarily to provide weather-tightness and support people and equipment. The deck serves as the lid to the complex box girder which can be identified as the hull. It resists tension, compression, and racking forces. The deck's scantling is usually the same as the topsides, or might be heavier if the deck is expected to carry heavier loa ...

Regia Marina
The ''Regia Marina'' (; ) was the navy of the Kingdom of Italy (''Regno d'Italia'') from 1861 to 1946. In 1946, with the birth of the Italian Republic (''Repubblica Italiana''), the ''Regia Marina'' changed its name to ''Marina Militare'' ("Military Navy"). Origins The ''Regia Marina'' was established on 17 March 1861 following the proclamation of the formation of the Kingdom of Italy. Just as the Kingdom was a unification of various states in the Italian peninsula, so the ''Regia Marina'' was formed from the navies of those states, though the main constituents were the navies of the former kingdoms of Sardinia and Naples. The new Navy inherited a substantial number of ships, both sail- and steam-powered, and the long naval traditions of its constituents, especially those of Sardinia and Naples, but also suffered from some major handicaps. Firstly, it suffered from a lack of uniformity and cohesion; the ''Regia Marina'' was a heterogeneous mix of equipment, standards and p ...

Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifled barrel, the distance is measured between opposing lands or between opposing grooves; groove mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Literal Translation
Literal translation, direct translation or word-for-word translation, is a translation of a text done by translating each word separately, without looking at how the words are used together in a phrase or sentence. In translation theory, another term for "literal translation" is '' metaphrase'' (as opposed to '' paraphrase'' for an analogous translation). Literal translation leads to mistranslating of idioms, which is a serious problem for machine translation. The term as used in translation studies Usage The term "literal translation" often appeared in the titles of 19th-century English translations of classical, Bible and other texts. Cribs Word-for-word translations ("cribs," "ponies" or "trots") are sometimes prepared for a writer who is translating a work written in a language they do not know. For example, Robert Pinsky is reported to have used a literal translation in preparing his translation of Dante's '' Inferno'' (1994), as he does not know Italian. Similarly, ...
